PDFs are a great archive format for scanned images, but Acrobat does not allow you to edit the text layer of the document (the part that can copy and paste from) leaving you with just the raw OCR. Are there any freeware alternatives that let you edit the text layer?

Even Adobe's own software is not good at doing this or making clear how to do it.
With Adobe Acrobat X, you can create a text layer through the menus (View | Tools | Recognize Text) or by click Tools in the toolbar and then Recognize Text in the Tools pane.
You then have options to perform OCR on the document or find "suspects". The "suspects" are possible OCR results that don't look right (don't spellcheck?). Once you have gone through the suspects, there doesn't seem to be any way to access or edit the text layer again short of redoing the OCR.
You can choose page ranges to limit OCR (e.g. if you have a multilingual document), but you can't limit it to a selection.
Given that this is such a useful feature, it's disappointing that Adobe don't make it very user-friendly.
Edit: Two other possible solutions.
Adobe Acrobat using ClearScan
When you perform OCR with Adobe Acrobat you can change the PDF Output Style from the default Searchable Image format to ClearScan. This format will actually change the image as well, replacing characters with outlines derived from the OCR. This would both make your PDF more readable and add a text layer, but it does change the original image.
Infix PDF Editor
This program does seem to be able to display the text layer, but it still seems tricky fixing places where Adobe's OCR goes wrong (e.g. lone words in their own positioned para).
Sadly none of these options are freely available.
Ehow tech posted three methods of converting Word documents to PDF (aka Portable Document Format) two of which I am sure work fine, not sure about Zamar.
Go to the Zamzar website. Zamzar provides free conversion to and from different formats. This option works well if you don't need to convert Word documents to PDF frequently.
Purchase and install Adobe Acrobat. At the time of publication, Adobe Acrobat Standard was selling for approximately $300 (now only $139).

Free PDF editors are very scarce.
The only free one I know is OpenOffice with Sun PDF Import Extension.
