- | The CDLI is a collaborative project with capture and text processing efforts underway in North America, Europe and the Middle East. We adhere to a policy of open access, making our data sets of text and images available over the internet to any user for free. We send scanning teams to collections whenever possible, but travel and personnel costs limit how much we can do. If you are a specialist who has created inscription annotations in the form of photos, hand copies, transcriptions or translations; | + | The [[http:// |
If you do decide to contribute your labor, please look over the following guidelines for scanning tablets and editing text hardcopies. You might first consider whether a given artifact in your possession requires conservation to achieve best imaging results. The first stage in this process would be, image the artifact as best you can (see below), send these results to us or another center of cuneiform research for inspection, and if deemed critical for the preservation of the artifact, of for understanding the text or seal impression that is carries, then seek out expert conservation assistance. If you have a lab in the vicinity that has experience in ancient artifact conservation, | If you do decide to contribute your labor, please look over the following guidelines for scanning tablets and editing text hardcopies.

- | (8) Edges are difficult to scan due to the fact that tablets do not naturally rest on their edges and a tablet that is standing on its edge could be damaged if it falls over onto the surface of the scanner. So it is always best to prop up a tablet on its edge by some means available to you. Ideally, the supporting props employed should be black in color with a matte finish. These black props then disappear or can more easily be erased when producing the archival "fat cross" representation of tablets chosen by the CDLI ([[http:// | + | (8) Edges are difficult to scan due to the fact that tablets do not naturally rest on their edges and a tablet that is standing on its edge could be damaged if it falls over onto the surface of the scanner.

(9) Keep your eyes on the surface of the scanner to detect the accumulation of dust and fingerprints (as noted above, careful placement of a tablet on the surface of the scanner often requires touching the surface of the scanner with the fingertips, so expect to clean up a lot of fingerprint smudges). Clear any tablets or props off the surface of the scanner, blow any dust or other particles off the surface and clean off any remaining fingerprints or smudges with a piece of lint-free cloth. | (9) Keep your eyes on the surface of the scanner to detect the accumulation of dust and fingerprints (as noted above, careful placement of a tablet on the surface of the scanner often requires touching the surface of the scanner with the fingertips, so expect to clean up a lot of fingerprint smudges).
