Take pictures of book pages

I too take pictures of book pages, although not as many as you.

I also take pictures of every document Im bringing: airline tickets, train tickets, museum tickets, passports, driver's licenses, birth certificates, etc etc. All of these are then in the cloud, and if I lose anything on the trip (because I pack the hard copies), I can find a computer and printer somewhere and retrieve them. Peace of mind.

I have a scanner and scan pages instead of taking pictures of them - which takes more time but gives me much better quality than a phone picture.

I would be very careful about scanning my personal documents like a birth certificate and just "putting them in the cloud" due to the potential for identity theft in the event cloud storage is compromised.

I agree with Andrew H. Scan documents where possible or convert to PDF if you have access to them electronically (email confirmation etc.)

Pictures are in color and also much higher resolutions. They take up way more space in your phone than scanned documents. And the quality of pictures is far lower.

Good idea about scanning. I scan my passport for a color copy and store it electronically, but haven't done this with books. I don't have a scanner but if I can get my act together and mark the proper pages in advance I can go to the library and use theirs.

You reminded me - converting web and email resources to PDF is another good tip. If there's an interesting website, or if you get tickets/confirmations as email attachments just hit print on your computer but instead of sending it to the printer choose "save as PDF". Then you save the PDF and can transfer it to your phone or wherever you'd like it. I send it to my kindle account (free) so I can access it anywhere the kindle or kindle app is logged in as me, and I can re-dowload it if it is somehow deleted or lost.

In the last few trips I have done this with a website about classic foods from Venice, a blog detailing how to return a car at Atocha station in Madrid, detailed directions to my apartment rental which was on a tiny unlabeled side alley, and train tickets bought in advance. Many other things, as well. The train tickets were also printed - I didn't know if the train accepted electronic copies of tickets, but since the PDF was scanned I could re-print it anytime and I didn't need to worry about spilling wine on the printout. Which is something I have done before.

By "pictures" I meant with the app Genius Scan... which automatically loads scanned docs into the cloud, so no taking up space on your phone...
I take your point about possible compromising of the cloud

On the first shot of my camera, I always take a picture of my "return label" and something written like "Reward For Return"

I also have a $9.00 USB (Emergency Contact USB) chain w/ tag that I store everything health related, including copies of passport, travel documents, my driver's license, insurance cards. MRI's, Medications, etc

The USB Tags Are Listed Under Accessories

Yes, I'd store the documents in the cloud if I needed to. Breaches if any, are rare.

I put a physical label on my camera batteries instead. It's too much of a pain to try to take a picture of a "label" with my info, because I format my camera memory cards every day after downloading the pics to my laptop (and then back them up to a second drive).

I'm not sure I would want all of that personal info about me on a USB thumb drive.

I've lost track of how many times someone's Gmail or Hotmail account has been compromised and resulted in "phishing" emails from their compromised account. That means their Google Docs and Microsoft Onedrive cloud storage is compromised, too. So no - breaches are extremely common, I'd say.

With Google, at least (maybe Microsoft too, not sure), you can setup "two factor authentication" which requires a code each time you login from a new device - the code is texted to you, so of course when traveling you'd need to be able to receive text messages. This should make your email account and cloud storage account much more secure, though.

I do this as well. It's good practice for people going on weekend trips, etc. I suggest this to everyone who doesn't format their cards everyday.

I'm not worried about having my personal data on a thumb drive. It has password protection and if you forget the password, there is no way to reset it.
