Follows the "certified teacher only" approach which is in Ciro Santilli's opinion a fatal flaw of most elearning systems out there, OurBigBook.com won't suffer from that!
All notes appear to have been extracted from existing notes, as noted on the bottom of each page.
Appears to have mixed licenses. E.g.:
- phys.libretexts.org/Bookshelves/University_Physics/Book%3A_University_Physics_(OpenStax)/Book%3A_University_Physics_III_-_Optics_and_Modern_Physics_(OpenStax)/06%3A_Photons_and_Matter_Waves/6.06%3A_De_Broglies_Matter_Waves is CC BY
- but we had seen another one that was CC BY-NC-SA
- phys.libretexts.org/Courses/University_of_California_Davis/UCD%3A_Physics_9HE_-_Modern_Physics/06%3A_Emission_and_Absorption_of_Photons/6.1%3A_Transitions_Between_Stationary_States CC BY-SA
- chem.libretexts.org/Bookshelves/Introductory_Chemistry/Introductory_Chemistry_(CK-12) uses the custom "CK-12 license" which seems a bit like CC BY-NC-SA
- some don't even have a free license, e.g.: phys.libretexts.org/Bookshelves/Quantum_Mechanics/Quantum_Mechanics_(Fowler)/00%3A_Front_Matter/04%3A_Licensing
TODO how does it work exactly? Do they ask for permission from authors in every case, including when the content has open license? Or when it has open license, do they just do it? In some cases, the notes have no license, so they must have asked.
TODO what is the source code that authors write? LaTeX or something else? LaTeX feels extremely likely given that it is what most original materials were already written in.
They are attempting a "model up this entire university" thing: phys.libretexts.org/Courses which is good. E.g. they have a bunch of "quantum mechanics ones under: phys.libretexts.org/Bookshelves/Quantum_Mechanics
Appears to be UC Davies-based mostly.
They claim to use this closed source backend: www.nice.com/resources/cxone-expert-knowledge-management? Seriously? For a publicly funded project with low-tech requirements?? It is mind blowing.
Some issues:
- the internal cross references are somewhat broken as of 2022.
- their URLs are HUGE! All components of every ancestor are in it. E.g. check this out: phys.libretexts.org/Bookshelves/Quantum_Mechanics/Introductory_Quantum_Mechanics_(Fitzpatrick)/12%3A_Time-Dependent_Perturbation_Theory/12.13%3A_Forbidden_Transitions Insane.
