How does the catalogue work?

Click the area of your choice, or search the complete catalogue using the search bar. To do this, enter a keyword and click 'Search'.

You can also search the catalogue by clicking an area on the homepage. You can refine your search results by clicking one or more of the various details.

Go to the appropriate area and check that the item isn't already in the catalogue. To be sure, use the search bar at top of each page to search too. For example, search for (part of) a title.

In the area pages, you'll see the option "Add item to catalogue". This option lets you insert information about the item. To do so, you need to be logged in. Fields that have an asterisk after them are mandatory. Finally, click the "Add" button below to actually add the item to the catalogue.

The catalogue works in a similar way to the wiki concept. This means that everybody is able to improve and adapt the content in the catalogue.

Click an item you want to change and in the menu on the right, click 'change item'. Then change the details and click the save button below the form.

The prices indicate the price at which the item in its current state could be bought or sold. These prices may be linked to the condition of the items. You should therefore pay close attention to the description of the condition.

You can search through the catalogue using the search bar or the area structure on the homepage. The area structure has three layers. There are the main areas such as comic strips, stamps and model cars. Beneath that are fields such as Author, Publisher and Artist, which categorise the subjects that collectors use for their collections. The final level contains the actual items. Examples are The Beatles, Vandersteen etc.

If you're missing a main area, go to contact page. We would be happy to put the area together with you. Within a main area such as Comic Strips, Music or Watches, you can add a new area by adding a new series, artist or brand at the lowest level.

The prices indicate the price at which the item in its current state could be bought or sold. This is about prices for which actual transactions have taken place, i.e. not about catalogue prices for which you receive a small fee when selling. These prices may be linked to the condition of the items. You should therefore pay close attention to the description of the condition.

Prices are defined by the moderators on the basis of their extensive practical experience. However, everybody can make price suggestions, for example because of personal selling or buying experience. If an item doesn't have a price yet, your price suggestion will immediately be applied and later reviewed by the moderators. If a price was already applied beforehand, your suggestion will be passed to the moderators.

Although the catalogue prices are up to date, there is always supply and demand for specific sales. This means it depends on where and how you offer your items. To obtain the catalogue prices, some patience may be needed. If you want to sell your items right away, you might have to accept a lower price. On the other hand, if you offer an item in a situation where people are trying to outbid each other, prices can even get higher than the catalogue price. Moderators like to hear your price suggestions on the basis of your selling and buying experiences.

Every condition describes characteristics that an item should comply with. To see this information, click the link "Explanation of conditions" which is below the information of an item.

Go to the appropriate area and check that the item isn't already in the catalogue. In the area pages, you'll see the option "Add item to catalogue". This option lets you insert information about the item. To do so, you need to be logged in. Fields that have an asterisk after them are mandatory. Finally, click the "Add" button below to actually add the item to the catalogue.

On the one hand, this is to make the website visually more attractive and more user-friendly. On the other hand, we like to make sure the item really does exist. We can verify this through the image.

Images should be in one of the following formats: .jpg, .gif, .png or .tiff. Pictures that exceed 700 pixels in height or width will be resized automatically. The largest file size that can be uploaded is 5MB. We recommend using .jpg files as they are compact and therefore load much faster. However, if an item does not have an image yet, we prefer that you add a small image rather than no image at all.

Click the item that you want to change in a photo gallery, list or showcase. You´ll then see the option ´Change item´ in the right-hand column and at the bottom of the page. Choose this option. Change the characteristics and click the ´Change´ button underneath. If you want to change the price indicated for an item, you can change it through "Specify price suggestion" by the item in the right-hand column or at the indicated prices. If a price was already set, your price suggestion goes to the moderators for review. Upon approval, your price will be reflected on the site. If you are the first to enter a price, your price is shown immediately and subsequently reviewed by the moderators.

If you want to change the indicated price of an item, choose the option "Give price suggestion". This option can be found in the right-hand column or by the indicated prices. If an item already has a price, your price will be reviewed by the moderators. If an item doesn't have a price yet, your price suggestion will immediately be applied and later reviewed by the moderators.

If an item already has a price, your price will be reviewed by the moderators. After confirmation, your price will be applied on the website.

Here you can see who added the item and what changes have been made. Every change results in a new version. Colours are used to indicate if a change has already been reviewed by a moderator and what the result was. Yellow means 'not reviewed yet'. Green is 'reviewed and confirmed'. Red means 'reviewed and rejected'. If rejected, the change will be undone.

A moderator should have experience in the areas he or she manages. In addition to that, a moderator is enthusiastic and willing to invest time in Catawiki in order to build the best collectors’ catalogue together.

We're aiming to have 5 to 10 moderators per area. However if there are already 10 moderators, but you do have experience and are enthusiastic about helping, we will be pleased to make an exception!

Probably - and thanks in advance for your interest. Please contact us through the contact page. We expect that a moderator will have experience in their particular collector’ area. In addition to that, a moderator is enthusiastic and willing to invest time in Catawiki in order to build the best collectors’ catalogue together. Of course a moderator will receive something in return.

No, we evaluate periodically whether the team of moderators for a particular area has the right composition.

Yes, of course. You can stop whenever you want.
