How to Search Digital Edition

To begin a search, choose the desired method in the "Search Methods" box at the right. Additional information about each search method can also be found by clicking on that method in the box. For general instructions and searching tips, click on "Search Instructions."
- Name/Date/Document Type
Use this method to find all documents containing a particular name (individual, institution, newspaper, etc.) in our database of approximately 23,500 names. This method can also be used to find all documents of a particular date or within a range of dates, as well as documents of a specific type (for example, correspondence, technical notes and drawings, accounts). It is also possible to search by a combination of names (up to four), dates, and document types.
- Folder/Volume Descriptions
Use this method to search for words or phrases in the descriptive introductions that the editors have prepared for each series, subseries, folder, and volume in the digital edition.
- Series Notes
Use this method to obtain a list of the folders and volumes in each series of the digital edition (for example, Notebook Series, Patent Series), as well as a list of the documents in a particular folder or volume. The images from Parts I-III of the microfilm edition (1850-1898) are available online and can be retrieved through the Series Notes. Although Parts IV-V (1899-1919) are not yet digitized, the document records for those two parts can be retrieved through the Series Notes. All of the documents in Parts I-V are from the archives of the Thomas Edison National Historical Park. The "Outside Repositories" series contains images of documents from the National Archives, Library of Congress, Smithsonian Institution, and numerous other repositories and private collections.
