This week's addition to the site counts 16 new documents. Several related to the F-4 Phantom, Fury, Sabre, CF-104, Basler, RR Spey and two Spitfire manuals scans provided by the Mike Potter's Collection. The Mike Potter Collection flies several warbirds from Gatineau, QC, Canada. You can check the website from their sister company, Vintage Wings of Canada.
You probably remarked that some manuals display a watermark, some not. If Avialogs scans the manual, it will display a watermark. Why? Because some people put them on sale on eBay, and while Avialogs distribute them under a creative common license, it includes a non-commercial clause. Manuals without watermark were received from contributors already scanned. This is also why the quality of documents can significantly vary.
With the new version coming up in August, it will be possible to upload manuals directly to the site.
