WELCOME to the Web version of the Index To How To Do It Information . The Index To How To Do It Information (HTDI Index) was created to aid public and college libraries in locating how-to articles in magazines to which they subscribe. Therefore, you must contact your local public library to see if they have the issue referred to by the index within their magazine collection or will secure a copy from another library. Also ask your librarian to provide you with the current address of the publisher of the magazine and check to see if the publisher can provide a copy of the article. In November 2012, the magazine collection accumulated by Norman Lathrop Enterprises and itemized in the UNION LIST was donated to the Akron-Summit County Public Library (60 S.High St., Akron OH 44326). For a fee, they may be willing to provide a copy of most articles cited in the HTDI Index. Contact them at 330-643-9075 or online at www.akronlibrary.org. New visitors to this site are encouraged to take a few minutes to read the Introduction, Organization, and Past & Future pages. Access to the Web version of the Index To How To Do It Information (HTDI) is being made freely available to individuals and institutions subject to the understanding that the entire HTDI Index is a copyrighted work and all rights are reserved to Norman Lathrop Enterprises (2342 Star Dr., Wooster OH 44691). The contents of this database, in whole or in part, may not be offered for sale by anyone except Norman Lathrop Enterprises. Online users of the HTDI Index are subject to monitoring by NLE using statistical and analytical programs. Access to the online version of the HTDI Index is offered solely at the discretion of Norman Lathrop Enterprises and access is not guaranteed to continue. The following two book formats of the Index To How To Do It Information are considered to be the only archival versions. |
