Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Scan pages in, clean them up in an image editor, save to individual files. Use this command to convert each page to PDF. Combine in Acrobat Professional, and use the built-in OCR with the "Searchable Image (Exact)" option. Gives excellent image quality and file size (avoids awful JPEG image recompression that Acrobat and other OCR systems tend to do.)

Use this to turn a page with snippets of equations into vector paths that Adobe Illustrator can handle without choking on font embedding and substitution issues. Good for keeping fonts consistent when labeling charts and diagrams. Also good for embedding formulas into diagrams.
