- Do you read many papers, but have trouble finding your copy in that large stack of paper printouts after a year?
- If you finally found it, do you often gaze at a printout without notes?
- Or when you just quickly found to find that one sentence in a paper, you do not find it because your comments are only in the hard copy?
- Do you often switch between reading papers from printouts and your computer?
## My solution: iPad + PDF Expert + sharecloud ( + zotero)
I solved these issues for myself by annotation the papers I read digitally. Either directly on the computer with the mouse, or with the Apple pencil when reading on my iPad. I store all papers in a `sharecloud` (MPG accounts have 50GB free) and use PDF Expert from https://readdle.com/ for iPad annotations. PDF Expert accesses the `.pdf` files via `webdav` from `sharecloud`.
On my local laptop I use zotero to manage papers. plugin to store directly with one click from browser.
