Frequently Asked Questions

  1. General information

 

    1. What is the Delet portal?

 

The mission of the Delet (Hebrew: ‘door’) portal is to share some of the most valuable items from the collections of the Main Judaic Library owned by the Association of the Jewish Historical Institute (AJHI) and the Jewish Historical Institute (JHI). The resources available on the portal include one of the most important and unique collections of modern art created by Polish Jews as well as items forming part of the collection documenting the life in the Jewish Ghetto (listed in the UNESCO Memory of the World Register). This is the first time that these collections are shared in full, in a form which is both cohesive and tailored to their nature.

The Delet portal allows logged-in users to work on the shared collections and create visually appealing educational materials – lessons and workshops – with the use of interactive tools available on the portal. This makes Delet a useful tool for educators, university students, and school pupils. The shared resources allow users to expand and supplement their knowledge of Jewish history and culture with the use of the collections of the JHI and the AJHI.

The portal also includes virtual curator tours and elaborations allowing the user, guided by virtual curators and scholars, to explore the resources shared on the portal and discover lesser-known details, interesting titbits of information, and the history of the collections.

The project is subsidised by the Ministry of Culture and National Heritage of Poland as part of the Digital Culture programme.

 

    1. What is the CJL?

 

The Central Jewish Library (CJL) is a digital repository of the collections of the Jewish Historical Institute. The mission of the CJL is to provide broad access to all collections of the JHI and offer a tool useful for historians, genealogists, and all people interested in the culture and history of Jews in Poland by presenting the collections in a broader historical context.

 

    1. What is the Association of the JHI?

 

The Association of the Jewish Historical Institute of Poland is the founder of the Delet portal. The AJHI is a non-governmental organisation working to preserve and commemorate the history and culture of Polish Jews and their contributions to international culture.

 

    1. What is the JHI?

 

The Emanuel Ringelblum Jewish Historical Institute is a partner and co-founder of the Delet portal. The JHI is a state-owned cultural institution. It is a research and documentation centre focusing on all aspects of Jewish history and culture in Poland. The Institute holds the largest collections of Jewish archival and library materials in Poland and owns a large collection of Jewish art.

  1. Lessons

 

    1. What are Lessons?

Lessons are a key functionality of the Delet portal which allows you to create and share virtual presentations based on visual materials available on the portal.

Lessons allow our users to get acquainted with Jewish history and culture in an easy and accessible way. The portal contains both lessons created by employees and collaborators of the AJHI and the JHI and those created by the users themselves.

    1. What kinds of Lessons are there?

 

      1. Lesson

A lesson is a material in the form of an educational presentation intended for secondary education students and anyone interested in Jewish history and culture. Each lesson should focus on a specific topic consistent with its title and describe it in an exhaustive way.

We suggest adding a set of questions at the end of each the lesson to help check if the audience has understood the content.

      1. Workshop

A workshop is a material in the form of an educational presentation intended for secondary education students and anyone interested in Jewish history and culture.

Workshops should encourage people to expand their knowledge, discover new resources and texts, and incentivise users to explore the material presented. A workshop does not have to present the subject in a comprehensive way but should encourage the audience to explore it on their own.

 

      1. Showing

The ‘Showing’ category includes curator’s tours around exhibitions held at the JHI or virtual exhibitions created specifically for the Delet portal. These are prepared by specialised curators and educators.

      1. Elaboration

 

Elaborations are materials based on the collections of the Delet portal. They have the form of scientific articles, essays, prose, etc, and are created by employees or collaborators of the JHI and the AJHI.

 

      1. What does the Delet logo on the lesson cover mean?

 

The Delet logo means that the lesson has been created by an employee or collaborator of the JHI and the AJHI.

Before adding tags to a lesson, it is best to read the lists of tags and of keywords provided in the Advanced Search tab.

 

      1. Why can I not create a showing or elaboration?

 

Showings and elaborations are specific types of lessons which can only be created by employees or collaborators of the JHI and the AJHI.

The cover includes one big square image and three circles.

 

      1. Someone else modified or added a tag to my lesson. How come?

 

The administration reserves the right to add tags to users’ lessons (to improve search results) and to proofread and make necessary corrections.

 

  1. My Collections / My Lessons

 

    1. Why is my collection / my lesson grey?

It means that the collection has been published or is in the process of verification by the administrator.

    1. How can I create a lesson / a collection in English?

 

You can select the language of a lesson during its creation or by editing metadata.

NOTE: Lessons in Polish are only displayed on the Polish version of the portal, and lessons in English – only on the English version.

The easiest way to create a lesson in two languages is to click the ‘Duplicate lesson’ button (see Point 8.3).

 

    1. What does the ‘Duplicate collection / lesson’ button do?

Clicking the ‘Duplicate lesson’ button produces an exact copy of the lesson with the same descriptions, images, and notes. The duplicated lessons can be modified freely. This allows you to make a backup copy of the lesson, make corrections to an already published lesson (which cannot be modified) as well as produce a template for the English translation of the lesson (unfortunately the system does not translate automatically, so we are counting on you!).

    1. How can I publish my lesson / collection on the Delet portal?

To publish a lesson / a collection, click on the ‘Click to manage the lesson/collection’ icon and then click ‘Publish.’ The lesson / collection will be forwarded to the administrator for proofreading. You can withdraw your request for publication before the administrator starts working on the lesson / collection. This will no longer be possible once the process of proofreading has started. From that moment on, you will only be able to duplicate the lesson.

    1. Can I publish a lesson without a cover?

No. Only lessons with added covers can be published.

    1. I have found an interesting article online; can I add pictures to it and publish it on the Delet portal?

No. All published content must be created by you. If you are quoting someone, you must provide a clear citation.

    1. How to change the metadata of an object?

It is impossible to change metadata of objects on the portal. If you notice a mistake, reach out to the administrator.

 

  1. Search

 

    1. How does the search function on the Delet portal work?

The search function on the Delet portal is divided into three modules: simple search in lessons, simple search in collections, and advanced search. You can search the portal by clicking on the magnifying glass icon on the right side of the screen.

    1. How can I search in Collections and Lessons simultaneously?

The search algorithm does not allow for simultaneous search in Collections and Lessons.

    1. What is advanced search?

Advanced search allows you to apply a precise set of searching criteria in Collections / Lessons. You can search by several terms simultaneously, apply filters, and sort search results.

    1. What does the ‘Promoted’ filter mean?

Promoted lessons are the most interesting or newest lessons on the Delet portal. They appear on top of the search results.

    1. Why can’t I find documents from the CJL on the Delet portal?
