In the page overview of the document, the pages with the note have a special designation. Notes are visible only to you and no one else can see them. You can add notes in the document view from the Note panel or through the icon on the left side of the screen. In the User Area (see point 6) you will find a list of all your notes.

There are 3 ways to create collections:
1. From the ‘My Collections’ tab (in the User Area or Collections) through the ‘Add Collection’ button.
2. With the plus button displayed when you hover over the object's thumbnail in the Collections tab or in the search results in the collections.
3. Directly in the document using the ‘Add object to collection’ button (left side of the screen).
To create a collection, you need to create a name and description for it. You can change the name and description of the collection at any time. However, after the publication it will not be possible anymore.

What are Lessons?
Lessons are the key functionality of the Delet portal that allows you to create and share virtual presentations based on visual materials posted on the portal.
Lessons allow you to get acquainted with Jewish history and culture in an easy and accessible way. The portal contains both lessons created by employees and co-workers of AJHI and JHI, as well as created by users.
What kinds of Lessons are there?
A lesson is a special prepared material having the character of an educational presentation, intended for high school students, junior high school students and anyone interested in Jewish history and culture. The lesson should focus on a specific topic consistent with its title and describe it in an exhaustive way.
We suggest that the lessons at the end have some questions to help check if the recipients have understood the content.
A workshop is a special prepared material that has the character of an educational presentation. It is intended for students or high school students and anyone interested in Jewish history and culture.
A workshop should encourage people to expand their knowledge, learn about additional materials and articles and encourage users to explore the material presented. The workshop does not have to present the subject as a whole, but it should be an incentive to become interested in it.
A Curatorial Lesson is a presentation of an exhibition that was presented at the JHI or a virtual exhibition, created specifically for the Delet portal. Specialized curators and educators prepare curatorial Lessons.
An Elaboration is based on the collections of the Delet portal. In Elaborations, Users will find scientific articles, essays, prose etc. Employees or coworkers of the JHI and the Association of the JHI prepare elaborations.
