{"value"=>"<p>Used in conjunction with the \"Alphabetical List of Correspondence\" file cards and the container listing in this finding aid, the mailbooks facilitate access to letters of particular individuals and organizations present within Schwimmer's correspondence. These mailbook indexes cover the years 1921 through 1948, and are arranged alphabetically within each year. Kept entirely in Hungarian in the earlier years, English information does appear in later volumes.</p> <p>Entries generally list name of correspondent with the case suffixes of \"-nek\" or \"-tõl\" added to each proper noun, indicating whether the letter was sent or received, respectively. The dates of the individual letters, and, occasionally, mailing addresses follow each entry.</p> <p>To access letters sent to, or received from ,a particular individual:</p> <p>Step 1. Beginning with the \"Alphabetical Index of Correspondence\" file cards in our reading room, locate the desired name and note the years in which letters were exchanged.</p> <p>Step 2. Consult Schwimmer's mailbooks for those years. The mailbooks are arranged in chronological order, and alphabetically within each year. The mailbook entry will provide an exact date of the correspondence (month, date and year).</p> <p>Step 3. Using this exact date, refer to the container list of this finding aid in order to determine the appropriate box.</p> <p>For letters received prior to 1921, researchers seeking individuals' correspondence will unfortunately need to review all boxes for the given year, as there are no mailbooks or index representing that period.</p>"}
