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.

Although the World Wide Web appears to have "everything", too often a web site disappears and takes with it the information being sought. For this reason, Norman Lathrop Enterprises considers the published books to be the only archival versions of the Index To How To Do It Information.
