Summary of Significant Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation: The consolidated financial statements include the accounts of the Company. Investments in entities in which the Company has at least a 20%, but less than a majority interest, are accounted for using the equity method of accounting. Investments in entities in which the Company has less than a 20% ownership and in which it does not exercise significant influence are accounted for using the cost method of accounting. All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates: The preparation of the Company's financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Reclassifications	Reclassifications: Certain prior year amounts have been reclassified to conform to the current year's presentation.
Book Overdrafts	Book Overdrafts: Under the Company's cash management system, a book overdraft balance exists for the Company's primary disbursement accounts. This overdraft represents uncleared checks in excess of cash balances in individual bank accounts. The Company's funds are transferred from other existing bank account balances or from lines of credit as needed to fund checks presented for payment. As of April 30, 2012 and April 30, 2011, book overdrafts of $35.6 million and $40.0 million, respectively, were included in Accounts and Royalties Payable in the Consolidated Statements of Financial Position.
Revenue Recognition	Revenue Recognition: The Company recognizes revenue when the following criteria are met: persuasive evidence that an arrangement exists; delivery has occurred or services have been rendered; the price to the customer is fixed or determinable; and collectability is reasonably assured. If all of the above criteria have been met, revenue is recognized upon shipment of products or when services have been rendered. Subscription revenue is generally collected in advance. The prepayment is deferred and recognized as earned when the related issue is shipped or made available online over the term of the subscription. Collectability is evaluated based on the amount involved, the credit history of the customer, and the status of the customer's account with the Company. When a product is sold with multiple deliverables, the Company accounts for each deliverable within the arrangement as a separate unit of accounting due to the fact that each deliverable is also sold on a stand-alone basis. The total consideration of a multiple-element arrangement is allocated to each unit of accounting based on the price charged by the Company when it is sold separately. The Company's multiple deliverable arrangements principally include WileyPLUS, the online teaching and learning environment for the Company's Global Education business which also includes a complete print or digital textbook for the course, as well as negotiated licenses for bundles of electronic content available on Wiley Online Library, the online publishing platform for the Company's STMS business. When the Company's electronic content is sold through a third party, the Company is generally not the primary obligor within the arrangement since it typically is not responsible for fulfilling the customer's order or handling any customer requests or claims. Accordingly, the Company will recognize revenue for the sale of its electronic content through third parties based on the amount billed to the end customer, net of any commission owed to the third party seller of the content. Revenue is also reported net of any amounts billed to customers for taxes which are remitted to government authorities.
Cash Equivalents	Cash Equivalents: Cash equivalents consist of highly liquid investments with an original maturity of three months or less and are stated at cost plus accrued interest, which approximates market value.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts: The estimated allowance for doubtful accounts is based on a review of the aging of the accounts receivable balances, historical write-off experience, credit evaluations of customers and current market conditions. A change in the evaluation of a customer's credit could affect the estimated allowance. The allowance for doubtful accounts is shown as a reduction of Accounts Receivable in the Consolidated Statements of Financial Position and amounted to $6.9 million and $19.6 million as of April 30, 2012 and 2011, respectively. The decrease was primarily due to the write-off of the Borders accounts receivable which was provided for in fiscal year 2011 as disclosed in Note 9.
Sales Return Reserves	Sales Return Reserves: The process which the Company uses to determine its sales returns and the related reserve provision charged against revenue is based on applying an estimated return rate to current year sales. This rate is based upon an analysis of actual historical return experience in the various markets and geographic regions in which the Company does business. The Company collects, maintains and analyzes significant amounts of sales returns data for large volumes of homogeneous transactions. This allows the Company to make reasonable estimates of the amount of future returns. All available data is utilized to identify the returns by market and as to which fiscal year the sales returns apply. This enables management to track the returns in detail and identify and react to trends occurring in the marketplace, with the objective of being able to make the most informed judgments possible in setting reserve rates. Associated with the estimated sales return reserves, the Company also includes a related reduction in inventory and royalty costs as a result of the expected returns. The decrease in the sales return reserve was principally driven by the Company's ongoing migration to eBooks, the elimination of the high return Borders account and inventory management by the Company's customers.
Inventories	Inventories: Inventories are carried at the lower of cost or market. U.S. book inventories aggregating $60.7 million and $60.1 million at April 30, 2012 and 2011, respectively, are valued using the last-in, first-out (LIFO) method. All other inventories are valued using the first-in, first-out (FIFO) method.
Reserve for Inventory Obsolescence	Reserve for Inventory Obsolescence: A reserve for inventory obsolescence is estimated based on a review of damaged, obsolete, or otherwise unsalable inventory. The review encompasses historical unit sales trends by title; current market conditions, including estimates of customer demand compared to the number of units currently on hand; and publication revision cycles. The inventory obsolescence reserve is reported as a reduction of the Inventory balance in the Consolidated Statements of Financial Position and amounted to $33.9 million and $36.9 million as of April 30, 2012 and 2011, respectively.
Product Development Assets	Product Development Assets: Product development assets consist of composition costs and royalty advances. Costs associated with developing a publication are expensed until the product is determined to be commercially viable. Composition costs represent the costs incurred to bring an edited commercial manuscript to publication, which include typesetting, proofreading, design, illustration costs, and digital formatting. Composition costs are capitalized and are generally amortized on a double-declining basis over their estimated useful lives, ranging from 1 to 3 years. Royalty advances are capitalized and, upon publication, are recovered as royalties earned based on sales of the published works. Royalty advances are reviewed for recoverability and a reserve for loss is maintained, if appropriate.
Shipping and Handling Costs	Shipping and Handling Costs: Costs incurred for shipping and handling are reflected in the Operating and Administrative Expenses line item in the Consolidated Statements of Income. The Company incurred $50.4 million, $52.5 million and $55.6 million in shipping and handling costs in fiscal years 2012, 2011 and 2010, respectively.
Advertising Expense	Advertising Expense: Advertising costs are expensed as incurred. The Company incurred $24.3 million, $27.1 million and $26.0 million in advertising costs in fiscal years 2012, 2011 and 2010, respectively.
Technology, Property and Equipment	Technology, Property and Equipment: Technology, property and equipment is recorded at cost. Major renewals and improvements are capitalized, while maintenance and repairs are expensed as incurred. Technology, property and equipment is depreciated using the straight-line method based upon the following estimated useful lives: Buildings and Leasehold Improvements - the lessor of the estimated useful life of the asset up to 40 years or the duration of the lease; Furniture and Fixtures - 3 to 10 years; Computer Hardware and Software - 3 to 10 years. Costs incurred for computer software developed or obtained for internal use are capitalized during the application development stage and expensed as incurred during the preliminary project and post-implementation stages. Costs incurred during the application development stage include costs of materials and services, and payroll and payroll-related costs for employees who are directly associated with the software project. Such costs are amortized over the expected useful life of the related software which is generally 3 to 6 years. Maintenance, training, and upgrade costs that do not result in additional functionality are expensed as incurred.
Allocation of Acquisition Purchase Price to Assets Acquired and Liabilities Assumed	Allocation of Acquisition Purchase Price to Assets Acquired and Liabilities Assumed: In connection with acquisitions, the Company allocates the cost of the acquisition to the assets acquired and the liabilities assumed based on the estimates of fair value for such items, including goodwill, other intangible assets and technology acquired. Such estimates include discounted estimated cash flows to be generated by those assets and the expected useful lives based on historical experience, current market trends, and synergies to be achieved from the acquisition and the expected tax basis of assets acquired. The Company may use an independent appraiser to assist in the determination of such estimates.
Goodwill and Intangible Assets	Goodwill and Intangible Assets: Goodwill is the excess of the purchase price paid over the fair value of the net assets of the business acquired. Intangible assets principally consist of brands, trademarks, content and publication rights, customer relationships and non-compete agreements. Goodwill and indefinite-lived intangible assets are not amortized but are reviewed annually for impairment, or more frequently if events or changes in circumstances indicate the asset might be impaired. The Company evaluates the recoverability of indefinite-lived intangible assets by comparing the fair value of the intangible asset to its carrying value. To evaluate the recoverability of goodwill, the Company uses a two-step impairment test approach at the reporting unit level. In the first step, the estimated fair value of the entire reporting unit is compared to its carrying value including goodwill. If the fair value of the reporting unit is less than the carrying value, a second step is performed to determine the charge for goodwill impairment. In the second step, the Company determines an implied fair value of the reporting unit's goodwill by determining the fair value of the individual assets and liabilities (including any previous unrecognized intangible assets) of the reporting unit other than goodwill. The resulting implied fair value of the goodwill is compared to the carrying amount and an impairment charge is recognized for the difference. Finite-lived intangible assets are amortized over their estimated useful lives. The most significant factors in determining the estimated life of these intangibles is the history and longevity of the brands, trademarks and content and publication rights acquired, combined with the strength of cash flows. Content and publishing rights that have an indefinite life are typically characterized by intellectual property with a long and well-established revenue stream resulting from strong and well-established imprint/brand recognition in the market. Content and publication rights, trademarks, customer relationships and brands with finite lives are amortized on a straight-line basis over periods ranging from 5 to 40 years. Non-compete agreements are amortized over the terms of the individual agreement, generally up to 5 years. Intangible assets with finite lives are amortized on a straight line basis over the following weighted average estimated useful lives: acquired publishing rights - 36 years; customer relationships - 20 years; brands and trademarks - 11 years; non-compete agreements - 3 years.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets: Assets with finite lives are only evaluated for impairment upon a significant change in the operating or macroeconomic environment. In these circumstances, if an evaluation of the projected undiscounted cash flows indicates impairment, the asset is written down to its estimated fair value based on the discounted future cash flows.
Derivative Financial Instruments	Derivative Financial Instruments: The Company, from time to time, enters into forward exchange and interest rate swap contracts as a hedge against foreign currency asset and liability commitments, changes in interest rates and anticipated transaction exposures, including intercompany purchases. The Company's derivatives are recognized as assets or liabilities and measured at fair value. Derivatives that are not determined to be effective hedges are adjusted to fair value with a corresponding charge to earnings. The Company does not use financial instruments for trading or speculative purposes.
Foreign Currency Gains/Losses	Foreign Currency Gains/Losses: The Company maintains operations in many non-U.S. locations. Assets and liabilities are translated into U.S. dollars using end of period exchange rates and revenues and expense are translated into U.S. dollars using weighted average rates. Foreign currency translation adjustments are accumulated and reported as a separate component of Accumulated Other Comprehensive Loss within Shareholders' Equity. The Company's significant investments in non-U.S. businesses are exposed to foreign currency risk. During fiscal year 2012, the Company recorded $30.2 million of foreign currency translation losses primarily due to the strengthening of the U.S. dollar relative to the British pound sterling and euro. Foreign currency transaction gains or losses are recognized in the Consolidated Statements of Income as incurred.
Share-Based Compensation	Share-Based Compensation: The Company recognizes share-based compensation expense based on the fair value of the share-based awards on the grant date, reduced by an estimate for future forfeited awards. As such, share-based compensation expense is only recognized for those awards that are expected to ultimately vest. The fair value of share-based awards is recognized in net income on a straight-line basis over the requisite service period. Share-based compensation expense associated with performance-based stock awards is based on actual financial results for targets established three years in advance. The cumulative effect on current and prior periods of a change in the estimated number of performance share awards, or estimated forfeiture rate, is recognized as an adjustment to earnings in the period of the revision.
Recently Issued Accounting Standards	Recently Issued Accounting Standards: In October 2009, the FASB issued ASU 2009-13 "Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements" ("ASU 2009-13"). ASU 2009-13 addresses the accounting for multiple-deliverable arrangements to enable vendors to account for products and services separately rather than as a combined unit. Specifically, this guidance amends the existing criteria for separating consideration received in multiple-deliverable arrangements, eliminates the residual method of allocation and requires that arrangement consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method. The guidance also establishes a hierarchy for determining the selling price of a deliverable, which is based on vendor-specific objective evidence; third-party evidence; or management estimates. Expanded disclosures related to the Company's multiple-deliverable revenue arrangements are also required. The new guidance was adopted by the Company for all revenue arrangements entered into or materially modified on and after May 1, 2011 and did not have a significant impact on the Company's consolidated financial statements. In May 2011, the FASB issued ASU 2011-04, "Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs" ("ASU 2011-04") which amends U.S. GAAP to provide common fair value measurement and disclosure requirements with International Financial Reporting Standards. The Company does not expect ASU 2011-04 to have a significant effect on its current fair value measurements within the consolidated financial statements, however, the new guidance will result in additional disclosures which will include quantitative information about the unobservable inputs used in all Level 3 fair value measurements. ASU 2011-04 will be effective for the Company as of May 1, 2012. There have been no other new accounting standards issued that have had, or are expected to have a material impact on the Company's consolidated financial statements.

Recently Issued Accounting Standards

Recently Issued Accounting Standards: In October 2009, the FASB issued ASU 2009-13 "Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements" ("ASU 2009-13"). ASU 2009-13 addresses the accounting for multiple-deliverable arrangements to enable vendors to account for products and services separately rather than as a combined unit. Specifically, this guidance amends the existing criteria for separating consideration received in multiple-deliverable arrangements, eliminates the residual method of allocation and requires that arrangement consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method. The guidance also establishes a hierarchy for determining the selling price of a deliverable, which is based on vendor-specific objective evidence; third-party evidence; or management estimates. Expanded disclosures related to the Company's multiple-deliverable revenue arrangements are also required. The new guidance was adopted by the Company for all revenue arrangements entered into or materially modified on and after May 1, 2011 and did not have a significant impact on the Company's consolidated financial statements.

In May 2011, the FASB issued ASU 2011-04, "Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs" ("ASU 2011-04") which amends U.S. GAAP to provide common fair value measurement and disclosure requirements with International Financial Reporting Standards. The Company does not expect ASU 2011-04 to have a significant effect on its current fair value measurements within the consolidated financial statements, however, the new guidance will result in additional disclosures which will include quantitative information about the unobservable inputs used in all Level 3 fair value measurements. ASU 2011-04 will be effective for the Company as of May 1, 2012.

There have been no other new accounting standards issued that have had, or are expected to have a material impact on the Company's consolidated financial statements.
